The bro's over at the French Station Drivers stumbled into new ForceWare drivers dated at the 30th or March. The download is a 15 meg sized file and does include an easy to install setup.exe in the extracted folder.
The good news is that it is a WHQL approved driver (Microsoft tested and verified). The bad news is that it's only for GeForce series 6. This driver has an included modified.inf file (courtesy of laptopvideo2go) for non-GeForce series 6 users.
Although WHQL these drivers are of course considered beta neither Guru3D.com or NVIDIA will take responsibility if anything fails. We recompressed the archive towards 15 MB. We suggest you give and read feedback on these drivers in our forums where it's being discussed right now in a dedicated thread.
